Active clinical trials for "Endocarditis"

Acute kidney injury is major complication after open heart surgery. The cause of acute kidney injury following open heart surgery is related to activation of sympathetic nervous system, decrease of renal blood flow, ischemia-reperfusion injury and systemic inflammatory response. Infective endocarditis patients undergoing open heart surgery have systemic inflammatory response associated with infective endocarditis. And the inflammatory response can be aggravated by cardiopulmonary bypass. The incidence of acute kidney injury following open heart surgery due to infective endocarditis was 50% in a previous report. And this acute kidney injury was related to the poor outcome and high mortality. Thus, the preventive method to protect kidney function will be needed in the patients with infective endocarditis undergoing open heart surgery. Dexmedetomidine is a selective α2-agonist and has sedative, analgesic, and CNS depressive effect. And several experimental study demonstrated the renal protective effect. Intraoperative dexmedetomidine administration can reduce the amount of anesthetics needed and suppress the sympathetic response resulted by surgical stimulation. And dexmedetomidine was reported to reduce the level of serum cortisol, epinephrine and norepinephrine during the operation. Thus, these effects of dexmedetomidine can be expected to reduce the incidence of acute kidney injury. Therefore, the investigators hypothesized that dexmedetomidine has renal protective effect and this effect might be related to the suppression of inflammatory response. Thus, the investigators will evaluate the incidence of acute kidney injury and the incidence of major adverse kidney events (MAKE) after open heart surgery due to infective endocarditis and the level of inflammatory mediators. The primary end point of this study is the incidence of acute kidney injury after open heart surgery due to infective endocarditis. And secondary end point is the incidence of MAKE, the level of cystatin C which is related to the renal function, the level of inflammatory mediator and the postoperative morbidities.

The purpose of this study is to monitor the safety and efficacy of CUBICIN under conditions of actual use in patients who are diagnosed with complicated Skin and Skin Structure infection (cSSI) or Staphylococcus aureus bacteria including right-sided endocarditis and are prescribed CUBICIN by their physician.

Infective endocarditis is a complex infection that can be life-threatening. These infections also cause anatomical lesions that can be severe. Their management is complex and involves several disciplines: cardiology, bacteriologists, infectious diseases specialists, radiologists, nuclear medicine specialists, cardiac surgeons, neurologists, pharmacologists, etc. The incidence of Enterococcus faecalis endocarditis is increasing due to the aging of the population and the disappearance of rheumatic fever. The adequate management of these infections is complex and relies on the prolonged administration of high-dose antibiotics, classically the combination of amoxicillin and ceftriaxone. In the context of Streptococcal endocarditis, the impact of increasing the Minimum Inhibitory Concentration (MIC) of amoxicillin on patient mortality has been demonstrated but no study has yet examined the impact of increasing the MIC of amoxicillin on the outcome of patients treated for Enterococcus faecalis infective endocarditis.

To evaluate the performance of a single high volume blood culture sampling strategy versus the actually used multiple sampling strategy for the diagnosis and categorization of infective endocarditis according to the Duke-Li classification in a Population of adults suspected of infective endocarditis.

Infectious endocarditis is a serious pathology with difficult diagnosis especially on prosthetic valves or cardiac device because of the plurality of clinical presentations and the low sensitivity value of echocardiography in these patients. Despite a well validated indication for the detection of septic emboli, the value of FDG-PET for the detection of prosthetic valves or cardiac implantable device is still unclear especially because of frequent non-septic inflammatory processes. To improve the specificity value, the use of radio-labeled leukocytes scintigraphy is conventionally proposed. An alternative method is to label leukocytes in vivo with an anti-murin anti body fragment ( Sulesomab , Leukoscan®). This scintigraphy is regularly used in the investigation of osteomyelitis and has been proposed in infectious endocarditis. To knowledge of investigators, the value of Leukoscan® scintigraphy on prosthetic valve or cardiac device infection had not been studied.

Primary objective: To describe the evolution of cerebral lesions in IE patients (number of patients with abnormal cerebral MRI in acute phase of IE and during follow-up).

The diagnosis of infective endocarditis is based on the results of blood culture and findings on transeosophageal echocardiography. Cardiac computarized tomography is a new modality, mainly used for the imaging of coronary arteries. Its use in the diagnosis of infective endocarditis is not well known.The purpose of this study is to establish the use of cardiac CT in infective endocarditis.

This study aims at studying the frequency of infective endocarditis after transcatheter aortic valve replacement/implantation

Cardiopulmonary surgery is associated with inflammatory responses that can lead to systemic inflammatory responses (SIRS), organ dysfunction (MOD) and death especially in patients with endocarditis. Cytokine removal might therefore improve outcomes of patients undergoing cardiac surgery. CytoSorb is a device designed to remove cytokine (IL-6, IL-10, TNFalpha) from the blood to reduce immune reactions. This trial investigates the use of CytoSorb during cardiac surgery in patients with endocarditis at the University Hospital Basel.

The hypothesis underlying this work is the identification of different sub phenotypes of patients with infective endocarditis through the study of the host's response to infection. Furthemore, metagenomic sequencing may be a helpful supplement to IE diagnostic, especially when conventional tests fail to yield a diagnosis.
